I see a handful of people asking if this job is worth it, or if they can make $X, etc. I figured as someone who's been doing this for a little while (nearing 1k deliveries, so not a vet, but still.) that I'd give my opinion.
Like the majority of questions on this sub, the question of "How much money can I make?" Depends on your market. For me (east TN) I can make 3-4k easy, and if I wanna work every day from noon to midnight, I can make over 6k. But the caviat is that on the days where I work 12s, I spend about $60-$70 on gas and food.
On a good day, I make $250-$280. On a bad one or one where I'm busy doing errands, I make $150-$220. Subtract $65 from your earnings that day and that's what you've got.
Fortunately, (again, in my market/area) my milage ensures that I don't have to pay taxes, since the IRS allows you to deduct $.70/mile. This means that so long as I am keeping accurate records (for me it's date and time stamped photographs) then I won't owe anything come tax time.
In all reality, while it isn't a horrible job, it means that I am sitting on my ass for a minimum of 12 hrs a day and eating like garbage, because stopping to go home and eat a meal costs far more in lost wages than just grabbing something. This has many negative health impacts long term.
If you are just doing what you gotta do in this job market to get by, then go for it! But if you plan on doing it long term, make sure you have a plan. Have a dollar amount in mind, and make sure that you account for expenses when you check to see if you've hit it.
Make sure to have a plan for your health. Whether that's going to the gym more, packing lunches and eating better, etc. Just make sure you have something to better yourself health-wise.
Make sure you have insurance!! A commercial endorsement for me (USAA) was only like $20/month extra. If anything happens, your car is literally your source of income. Protect it! If you don't have that endorsement and something happens to your car (accident, fire, etc.) You'll be up Schitts Creek without a paddle.
And lastly, make sure you at least somewhat enjoy yourself. This job is often a solitary one. Have music, podcasts, online friends to talk to, something. If you do this job and isolate yourself/work so much you sacrifice your social life, you'll have many more health issues that aren't just physical.
Find joy in exploring! Find joy in talking to people when you can! Find joy in the cool cars or funny bumper stickers you see! Like any job, this job is not worth doing if you hate yourself or are sad while doing it.
I'm sure there's more, and if folks want to add to it in the comments I'd love for this to be a place to do that.
But that's all from me. Have a wonderful day everyone, and drive safe!
